Rock 'n Roll HOF has a very wiiiiiiiiiiiiiide definition, like those crazy rockers Simon and Garfunkel, so let them have their fun. I like the choice of Donovan, definetly not a "rocker" but he had a major influence on the folkie scene in the 60's. (The call me(?) Mellow Yellow) It's funny how different organizations define "Hall of Fame". Baseball is all about stacking up statistics via longevity. Not sure what the R&R criteria is.
